1. A method for controlling an internal combustion engine system so as to avoid turbo surge and/or shorten power cut off during gearshift, wherein the internal combustion engine system comprises:
an internal combustion engine and a gearbox operatively connected to the internal combustion engine;
a turbocharging arrangement configured to provide a boost pressure of air fed to the internal combustion engine; and
a control system configured to control operation of the internal combustion engine system, the method comprising:
providing information about i) a point of time for initiating an upcoming gearshift, ii) a target engine speed after the upcoming gearshift, iii) a target engine torque after the upcoming gearshift, and iv) current operation conditions of the internal combustion engine system;
determining, based on said information and before the upcoming gearshift is initiated, whether there is a risk of having turbo surge during the upcoming gearshift; and,
if such a risk is determined,
lowering the boost pressure before initiating the upcoming gearshift.
